Total Organic Carbon (TOC) is an indicator that reflects the total amount of organic pollutants in water quality and is attracting more and more attention. Compared with the traditional determination of chemical oxygen demand (COD), TOC technology is simple and fast. The analysis time of a TOC analyzer is generally 4-6 minutes, and the TOC sensor CheckPoint can be as fast as 15 seconds. The fast detection speed makes TOC online monitoring widely used, and it can detect water quality abnormalities in a timely manner, indicating problems in the water system or sewage treatment system.

The system is mainly composed of TOC sensors, electric control boxes, servers and monitoring software. CheckPoint TOC sensors collect data, the electric control system transmits data, and the monitoring server is responsible for saving and processing data, so as to achieve the purpose of real-time online data monitoring. It can also provide various auxiliary functions, such as:TOC historical data query, chart generation, operation records, alarm warning, etc., to help users find, analyze and solve problems in time.

Field Application

Online monitoring of TOC is currently mainly used in pure water production systems and wastewater treatment and discharge for environmental monitoring. The application industries are mainly pharmaceutical, electronic, tap water, environmental monitoring, wastewater treatment, chemical, petrochemical and other fields. At present, most industrial water treatment uses membrane technology, and the organic content in the process is one of the key factors that determine the success and stable operation of the water treatment system. Real-time online monitoring and control of TOC in the water treatment process can monitor the removal rate of organic matter by process equipment such as activated carbon, reduce the frequency of membrane cleaning, and optimize the water treatment operation process, thereby reducing the operating cost of the water treatment system.
